The following is a summary of “Comparison of different surface treatment methods on flexural strength and elasticity modules of quartz and glass fiber-based posts: A narrative review,” published in the December 2022 issue of Primary care by Meimandinezhad, et al.

It was crucial to assess how various surface treatment techniques affected the flexural strength (FS) and elasticity modules (EM) associated with fiber posts. In the form of narrative review research, the primary goal of researchers was to assess the impact of various surface treatment techniques on the FS and EM of quartz and glass fiber-based posts.

In order to perform the study, a thorough search of all articles published between 2022 and 2000 that dealt with the topic at hand was conducted in databases that were accessible globally, including Web of Science, Science Direct, Scopus, PubMed, and Google Scholar. Finally, papers that were wholly pertinent to the main purpose were chosen for investigation.

The findings demonstrated that quartz fiber-based posts had higher FS and elasticity coefficients (EC) than glass fiber before surface treatment. The surface treatment of glass and quartz fiber posts using a laser and 10% hydrogen peroxide, according to the findings of several earlier investigations, has no impact on their FS and elasticity. The results of previous experiments demonstrated that the laser approach, as opposed to air abrasion, can be a more acceptable way for preparing the surface of fiber posts prior to the bonding process. There had been reports from other research claiming that the laser caused less FS than the airborne-particle abrasion (Al₂O₃) approach.

Based on the findings of prior research of a similar kind, it can be deduced that the findings of past research were very conflicting, and it was thus impossible to offer a truly superior surface treatment strategy to boost flexural strength. Flexural strength was mostly determined by the fiber post’s inherent characteristics.
